Abstract
To provide a display which can improve viewing angle dependency of a contrast ratio at least in a specific azimuth without design change of a basic structure of a display element, limitation to white display state or black display state, and deterioration in display quality in other directions. The above-mentioned display is a display comprising: a display element with a contrast ratio dependent on a viewing angle; and an anisotropic scattering film having an anisotropic scattering layer, wherein the anisotropic scattering film is located on a viewing screen side of the display element and has a scattering central axis in substantially the same azimuth as an azimuth in which a contrast ratio of the display element in a direction inclined by a certain angle from a normal direction of a viewing screen of the display element has an extreme value.
